<pre>In lldb/source/Expression/DWARFExpression.cpp, GetOpcodeDataSize(),
DW_OP_call_ref is handled in the same way as DW_OP_addr:
switch (op) {
case DW_OP_addr:
case DW_OP_call_ref: // 0x9a 1 address sized offset of DIE (DWARF3)
return data.GetAddressByteSize();
According to the DWARF standard, the operand size of DW_OP_call_ref is 4 or 8
bytes depending on the DWARF format (32- or 64-bit) and not an address size on
the target machine, as for DW_OP_addr.
Admittedly, I do not have a sample. I found that reviewing the code.</pre>
